Step 1: Begin by understanding the concept of simple interest. Simple interest is calculated only on the original principal amount, meaning the interest does not compound or accumulate over time.
Step 2: Understand the concept of compound interest. Compound interest is calculated on the principal amount plus any accumulated interest from previous periods, meaning the interest compounds over time.
Step 3: Compare the two concepts. The primary difference lies in how the interest is calculated: simple interest does not take into account accumulated interest, while compound interest does.
Step 4: Eliminate incorrect options based on the definitions. For example, simple interest does not decrease over time, nor is it limited to loans. Similarly, compound interest is not restricted to investments, and the frequency of calculation (annually or monthly) is not the defining difference.
Step 5: Identify the correct answer: 'Simple interest is calculated only on the original principal, while compound interest is calculated on the principal plus any accumulated interest.' This aligns with the definitions provided.
